[0017] The present invention also provides a method for using a power supply system fault detection device, comprising the following specific steps:

[0018] Step 1: When the detector body is placed on the ground, the positioning rods will contact the ground. The symmetrical positioning rods use the principle of a balance rod seesaw to adjust the up and down positions of the two positioning rods according to the flatness of the ground. When the ground where the positioning rod on the right is placed is lower than the height of the right placement surface, the positioning rod on the left will contact the ground first, and then be squeezed by the ground, causing the balance rod to rotate clockwise, prompting the positioning rod on the right to continue to move downward. When the right positioning rod moves downward, it will drive the first limit rod and the second limit rod to rotate, so that the right The angle between the relative ends of the first limit rod and the second limit rod increases, thereby being able to support the positioning rod on the right side. When the positioning rod on the right side contacts the ground and the bottom end of the detector body is in the same straight line, the rod body is moved toward the first limit rod and the second limit rod, thereby prompting the limit block to be inserted and engaged with the limit groove, so that the first limit rod and the second limit rod cannot rotate in the inner cavity of the rod body, and the positions of the first limit rod and the second limit rod after being unfolded can be fixed, thereby ensuring the stability of the balanced support of the detector body;

[0019] Step 2: After the detector body is placed in a balanced position, according to the height requirement of the detector body, the second support slot can be lifted by rotating the support rod, thereby prompting the detector body to rise in position. The support rod is cross-shaped, and one end of the support rod is movably arranged in the inner cavity of the first support slot through the insertion rod, and the other end of the support rod is hinged to the inner wall of the first support slot. By driving the connecting shaft, the connecting shaft rotates and drives the synchronous rotation of the reel, so that the drive rope can be reeled in, so that the drive rope generates tension on the insertion rod. The insertion rod is fixed to one end of the support rod, and can drive the support rod to move along the trajectory of the insertion slot. The support rod will rotate during the movement, so that the lifting force generated by the rotation drives the second support slot and the detector body to rise in position.

[0020] Step 3: When the detector body is opened for use, it is necessary to press the block first to move the block toward the inner cavity of the locking rod, thereby releasing the restriction between the locking rod and the locking block, so that the locking rod moves downward under the support of the spring's rebound force, thereby separating the locking rod from the locking block, thereby avoiding affecting the opening and use of the detector body.

[0021] Technical effects and advantages of the present invention:

[0022] (1) The present invention utilizes a supporting structure and an adjusting structure in combination to enable the height of the detector body to be adjusted according to the needs of use when in use, thereby being better adapted to the operation of the operator and providing convenience for the use of the detector body. At the same time, the adjusting structure can adjust the balance of the detector body when the placement surface of the detector body is uneven, thereby avoiding the phenomenon of tilting of the detector body due to uneven placement of the bottom end during use, effectively improving the stability of the placement of the detector body, and further enhancing the safety and effectiveness of the use of the detector.

[0023] (2) The present invention utilizes the arrangement of the drive structure to provide a driving force for the support height of the support structure, so that the support rod can indirectly rotate itself by reeling in and out the drive rope, thereby enabling support at different heights, effectively improving the convenience of using the support structure, thereby also enhancing the range of height adjustment of the detector body and improving the flexibility of height adjustment of the detector body;

[0024] (3) The present invention utilizes the setting mode of the locking structure to ensure the stability of the closure of the detector body when not in use. At the same time, it can also restrict the support structure to prevent the support structure from moving when not in use, thereby enhancing the stability and safety of the storage and movement of the detector body.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The present invention provides Figure 1-8 A power supply system fault detection device shown includes a detector body 1, and the bottom end of the detector body 1 is movably provided with a support structure 2 and a symmetrical adjustment structure 4, the support structure 2 includes a second support groove 202, a first support groove 201 and an insertion component, the second support groove 202 is fixedly sleeved on the bottom end of the detector body 1, the first support groove 201 is movably sleeved on the outer wall of the second support groove 202, and a support rod 203 is symmetrically and movably provided between the first support groove 201 and the second support groove 202, the insertion component is provided between the support rod 203 and the first support groove 201, and the insertion component is used to limit the position of the lateral movement of the support rod 203, the insertion component includes an insertion rod 204 and an insertion slot 205, the insertion slot 205 is opened on one side of the first support groove 201, the insertion rod 204 is movably inserted in the inner cavity of the insertion slot 205 and is fixedly inserted with one end of the support rod 203, and a plurality of balls are fixedly provided on the outer wall of the insertion rod 204.

[0036] like Figure 1 and Figure 3 As shown in , the second support groove 202 is fixed to the bottom end of the detector body 1 by any fixing method such as a screw or a screw. When the detector body 1 is not in use, the first support groove 201 is sleeved on the outside of the second support groove 202. There are two groups of support rods 203 between the first support groove 201 and the second support groove 202. One group of support rods 203 is two support rods 203 arranged at a cross position, as shown in FIG. Figure 3As shown in the figure, one end of the support rod 203 located at the bottom end of the inner cavity of the first support groove 201 in one group can move laterally. On the contrary, one end of the support rod 203 located at the bottom end of the second support groove 202 in the other group can move laterally. In this way, it can ensure that the support rod 203 can stably support the second support groove 202 and the detector body 1 when rotating.

[0037] like Figure 1 and Figure 8 As shown in the figure, one end of the insertion rod 204 is fixed to one end of the support rod 203, and the other end of the insertion rod 204 passes through the inner cavity of the insertion slot 205 and extends to one side of the first support slot 201. The inner cavity of the insertion slot 205 is connected to the outer wall and the inner cavity of the first support slot 201, so that the support rod 203 can move by using the movement of the insertion rod 204. At the same time, a ball is fixed to the outer wall of the insertion rod 204, and the outer wall of the ball contacts the inner wall of the insertion slot 205, so that the movement of the insertion rod 204 reduces the friction with the insertion slot 205, and also provides guidance for the movement of the insertion rod 204 and the support rod 203, ensuring the effectiveness and smoothness of the lateral movement of the support rod 203. In summary, under the setting of the support structure 2, the detector body 1 can flexibly adjust its own height when in use, thereby making it more convenient for the operator to use the detection, thereby effectively improving the convenience and flexibility of the use of the detector body 1.

[0038] The adjustment structure 4 includes two positioning rods 401, a balance rod 402, a support frame 403 and a symmetrical limit assembly. The two positioning rods 401 are fixedly arranged at both ends of the balance rod 402, the support frame 403 is movably inserted in the middle of the balance rod 402, and the limit assembly is arranged between the positioning rod 401 and the first support groove 201.

[0039] like Figure 3 and Figure 4 As described above, the balance bar 402 utilizes the support principle of the support frame 403 like a seesaw, so that when the position of the positioning rod 401 at one end of the balance bar 402 rises, it will prompt the positioning rod 401 at the other end to fall. The support frame 403 is I-shaped, which can provide support for the balance bar 402 while preventing the balance bar 402 and the support frame 403 from falling off. When the detector body 1 is placed on an uneven ground, the detector body 1 can be balanced by the reverse movement of the positioning rod 401 and the cooperation of the limit assembly, so that the detector body 1 remains in a horizontal state, avoiding the phenomenon of the tilted detector body 1 tipping over during use.

[0040] The limiting assembly includes a first limiting rod 404, a second limiting rod 405 and a rod body 406. The ends of the first limiting rod 404 and the second limiting rod 405 that are separated from each other are hinged to the positioning rod 401 and the first support groove 201 respectively. The opposite ends of the first limiting rod 404 and the second limiting rod 405 are hinged to each other. The rod body 406 is movably inserted between the opposite ends of the first limiting rod 404 and the second limiting rod 405. A positioning member is provided on the outside of the rod body 406. The positioning member includes a plurality of limiting blocks 407 and a plurality of limiting grooves 408. The plurality of limiting blocks 407 are fixedly arranged at equal intervals on the outer wall of the rod body 406, and the plurality of limiting grooves 408 are opened at equal intervals on the inner walls of the opposite ends of the first limiting rod 404 and the second limiting rod 405.

[0041] like Figure 3 、 Figure 4 and Figure 5 As shown in the figure, the middle parts of the opposite ends of the first limiting rod 404 and the second limiting rod 405 are movably sleeved on the outer wall of the rod body 406. Under the support of the rod body 406, the first limiting rod 404 and the second limiting rod 405 can be hinged to each other. As the positioning rod 401 rotates, the first limiting rod 404 and the second limiting rod 405 will also rotate. When the position of the positioning rod 401 drops, the angle between the first limiting rod 404 and the second limiting rod 405 will increase, and vice versa. After the position of the positioning rod 401 changes, in order to ensure the balance of the support for the detector body 1, the moving rod 401 can be used to adjust the position of the first limiting rod 404 and the second limiting rod 405. The body 406 causes the rod body 406 to move toward the first limit rod 404 and the second limit rod 405, thereby driving the limit block 407 to move toward the inner cavity of the limit groove 408. Through the engagement of the limit block 407 and the limit groove 408, the first limit rod 404 and the second limit rod 405 and the rod body 406 are kept in a fixed state. As a result, the first limit rod 404 and the second limit rod 405 can be prevented from rotating due to gravity, thereby ensuring the stability of the support for the detector body 1. At the same time, the detector body 1 is also suitable for a variety of placement ranges, which greatly improves the safety of the use of the detector body 1.

[0042] A driving structure 3 is arranged between the insertion rod 204 and the first support groove 201. The driving structure 3 includes a reel 302, a connecting shaft 303, a driving rope 301 and a protective cover 306. The reel 302 and the connecting shaft 303 are both arranged in the inner cavity of the protective cover 306. The protective cover 306 is fixedly arranged on the back side of the first support groove 201. The driving rope 301 is fixedly arranged between the reel 302 and the insertion rod 204. The reel 302 is rotatably arranged on the back side of the first support groove 201. The connecting shaft 303 is fixedly arranged in the middle of the reel 302.

[0043] like Figure 3 and Figure 6As shown in the figure, the reel 302 is rotatably arranged in the inner cavity of the protective cover 306 through the connecting shaft 303, and one end of the connecting shaft 303 passes through the middle of the reel 302 and is movably interlaced with one side of the protective cover 306, and one end of the connecting shaft 303 is driven by a driving motor, which provides an effective driving force for the rotation of the reel 302. Through the rotation of the reel 302, the driving rope 301 can be reeled and unreeled, so that when the driving rope 301 and the insertion rod 204 are fixed, the insertion rod 204 can be driven to move along the inner cavity of the insertion slot 205, and then the one end of the support rod 203 can be driven to move horizontally, and the other end of the support rod 203 will rotate, thereby ensuring that the support rod 203 effectively lifts the second support slot 202 and the detector body 1.

[0044] The inner cavity of the protective cover 306 is movably provided with two synchronous wheels 304 and a synchronous belt 305. The synchronous belt 305 is transmitted between the two synchronous wheels 304. The synchronous wheels 304 and the end of the connecting shaft 303 facing away from the reel 302 are fixed. A fastening rope is fixed at the top of the protective cover 306, and the top of the fastening rope is fixed to the back of the detector body 1.

[0045] like Figure 6 As shown in the figure, the setting of the two synchronous wheels 304 is adapted to the setting of the two groups of support rods 203, so that the two groups of support rods 203 can move synchronously, thereby improving the stability of the support of the detector body 1. The top of the detector body 1 is hinged with a box cover, and the top of the fastening rope is fixed to the back of the box cover of the detector body 1. Because the position of the detector body 1 will rise under the movement of the support rods 203, the two ends of the fastening rope are respectively fixed to the box cover and the protective cover 306, and the fastening rope is inclined, so that the box cover can be opened while the position of the detector body 1 rises, thereby improving the efficiency of the use of the detector body 1, and further enhancing the efficiency of power supply system fault detection.

[0046] A locking structure 5 is provided on both sides of the detector body 1, and the locking structure 5 includes a locking rod 501, a locking block 502, a mounting block 503 and a stop block 505. The mounting block 503 and the locking block 502 are fixedly arranged on one side of the detector body 1, and the locking rod 501 and the mounting block 503 and the locking block 502 are movably interspersed. The stop block 505 is movably arranged on the outer wall of the locking rod 501. The locking structure 5 also includes a stop rod 506 and two springs 504. The two springs 504 are fixedly sleeved on the outer walls of the stop rod 506 and the locking rod 501, and the stop rod 506 and the mounting block 503 are movably interspersed.

[0047] like Figure 1 、 Figure 2 and Figure 7As shown in the figure, after the locking rod 501 and the locking block 502 are intertwined with each other, they are restricted by the stopper 505, so that the box cover and the detector body 1 can be firmly closed, ensuring the stability of the closure during the storage and retrieval of the detector body 1. A spring 504 is also fixedly provided between the stopper 505 and the locking rod 501, and the outer wall of the locking rod 501 is provided with a groove for the stopper 505 to move. Under the action of external force, the stopper 505 can use the compression performance of the spring 504 to move toward the inner cavity of the groove, so that the locking rod 501 and the locking block 502 can be separated. A spring 504 is fixedly provided between the locking rod 501 and the mounting block 503, so that the locking rod 501 can be mounted on the mounting block 5 03 is movably inserted into the inner cavity, and the bottom end of the locking rod 501 passes through the bottom end of the mounting block 503 and extends downward, so that the locking rod 501 can move up and down, thereby facilitating the unlocking and locking of the detector body 1. The setting of the blocking rod 506 restricts the insertion rod 204 before it moves, so that when the detector body 1 is stored or moved, or when the connecting shaft 303 is not connected to the drive motor, the insertion rod 204 can be prevented from moving along the insertion slot 205 during the movement, thereby avoiding the separation between the first support slot 201 and the second support slot 202, thereby improving the stability of the support structure 2 when it is not in use, and also providing convenience for the storage and movement of the detector body 1.

[0048] The present invention also provides a method for using a power supply system fault detection device, comprising the following specific steps:

[0049] Step 1: When the detector body 1 is placed on the ground, the positioning rod 401 will contact the ground. The symmetrical positioning rods 401 use the seesaw principle of the balance rod 402 to adjust the upper and lower positions of the two positioning rods 401 according to the flatness of the ground. When the ground on which the positioning rod 401 on the right is placed is lower than the height of the right placement surface, the positioning rod 401 on the left will contact the ground first, and then be squeezed by the ground, causing the balance rod 402 to rotate clockwise, prompting the positioning rod 401 on the right to continue to move downward. When the right positioning rod 401 moves downward, it will drive the first limiting rod 404 and the second limiting rod 405 to rotate, so that the first limiting rod 401 on the right 4 and the second limiting rod 405 relative ends increase, thereby being able to support the right positioning rod 401, when the right positioning rod 401 is in contact with the ground and the bottom end of the detector body 1 is in the same straight line, by moving the rod body 406, the rod body 406 is moved toward the first limiting rod 404 and the second limiting rod 405, thereby being able to promote the interpenetration and engagement of the limiting block 407 with the limiting groove 408, so that the first limiting rod 404 and the second limiting rod 405 cannot rotate in the inner cavity of the rod body 406, thereby being able to fix the positions of the first limiting rod 404 and the second limiting rod 405 after being unfolded, thereby being able to ensure the stability of the balanced support of the detector body 1;

[0050] The second end of the support rod 203 is hinged to the inner wall of the first support groove 201, and the other end of the support rod 203 is hinged to the inner wall of the first support groove 201. By driving the connecting shaft 303, the connecting shaft 303 rotates and drives the reel 302 to rotate synchronously, so that the driving rope 301 can be reeled in, so that the driving rope 301 generates a pulling force on the insertion rod 204. The insertion rod 204 is fixed to one end of the support rod 203, and can drive the support rod 203 to move along the trajectory of the insertion slot 205. The support rod 203 will rotate during the movement, so that the lifting force generated by the rotation drives the second support groove 202 and the detector body 1 to rise.

[0051] Step 3: When the detector body 1 is opened for use, it is necessary to press the block 505 first to move the block 505 toward the inner cavity of the locking rod 501, thereby releasing the restriction between the locking rod 501 and the locking block 502, so that the locking rod 501 moves downward under the support of the rebound force of the spring 504, thereby separating the locking rod 501 from the locking block 502, thereby avoiding affecting the opening and use of the detector body 1.

[0052] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.

10. A method for using a power supply system fault detection device according to any one of claims 1 to 9, characterized in that: The specific steps are as follows: Step 1: When the detector body (1) is placed on the ground, the positioning rod (401) will contact the ground. The symmetrical positioning rods (401) use the seesaw principle of the balance rod (402) to adjust the upper and lower positions of the two positioning rods (401) according to the flatness of the ground. When the ground on which the positioning rod (401) on the right side is placed is lower than the height of the right placement surface, the positioning rod (401) on the left side will first contact the ground, and thus be squeezed by the ground, causing the balance rod (402) to rotate clockwise, prompting the positioning rod (401) on the right side to continue to move downward. When the position of the right positioning rod (401) moves downward, it will drive the first limiting rod (404) and the second limiting rod (405) to rotate, so that the first limiting rod (404) and the second limiting rod (405) on the right side are rotated. The angle between the two limiting rods (405) and the relative ends increases, thereby being able to support the right positioning rod (401). When the right positioning rod (401) contacts the ground and the bottom end of the detector body (1) is in the same straight line, the rod body (406) is moved so that the rod body (406) moves toward the first limiting rod (404) and the second limiting rod (405), thereby enabling the limiting block (407) to be inserted and engaged with the limiting groove (408), thereby preventing the first limiting rod (404) and the second limiting rod (405) from rotating in the inner cavity of the rod body (406), thereby being able to fix the positions of the first limiting rod (404) and the second limiting rod (405) after being unfolded, thereby ensuring the stability of the balanced support of the detector body (1); Step 2: After the detector body (1) is placed in a balanced position, according to the use height requirement of the detector body (1), the second support groove (202) can be generated by rotating the support rod (203), thereby promoting the detector body (1) to rise in position. The support rod (203) is in a cross shape, and one end of the support rod (203) is movably arranged in the inner cavity of the first support groove (201) through the insertion rod (204), and the other end of the support rod (203) is hinged to the inner wall of the first support groove (201). By driving the connecting shaft (303), the second support groove (202) can be lifted. ), so that the connecting shaft (303) rotates and drives the reel (302) to rotate synchronously, thereby being able to reel in the driving rope (301), so that the driving rope (301) generates a pulling force on the insertion rod (204), and the insertion rod (204) is fixed to one end of the support rod (203), thereby being able to drive the support rod (203) to move along the trajectory of the insertion slot (205), and the support rod (203) will rotate during the movement, so that the lifting force generated by the rotation drives the second support slot (202) and the detector body (1) to rise in position. Step 3: When the detector body (1) is opened for use, it is necessary to first press the block (505) to move the block (505) toward the inner cavity of the locking rod (501), thereby releasing the restriction between the locking rod (501) and the locking block (502), so that the locking rod (501) moves downward under the support of the rebound force of the spring (504), thereby enabling the locking rod (501) to separate from the locking block (502), thereby avoiding affecting the opening and use of the detector body (1).
